The utility model provides a based on hot and cold water natural layering circulation heat accumulation equipment 100.
Referring to fig. 1 and 3, in an embodiment of the present invention, the heat storage device 100 based on cold and hot water natural layering circulation includes:
a housing 10, wherein the housing 10 has a water storage space 11, the housing 10 is provided with a first water inlet outlet 10a and a second water inlet outlet 10b which are communicated with the water storage space 11, the first water inlet outlet 10a is arranged at the upper end of the housing 10, the second water inlet outlet 10b is arranged at the lower end of the housing 10, and the first water inlet outlet 10a and the second water inlet outlet 10b are both communicated with the water storage space 11;
the first water distribution pipe 30 is arranged in the water storage space 11 and is positioned at the upper end of the shell 10, one end of the first water distribution pipe 30 is communicated with the first water inlet 10a, and the first water distribution pipe 30 is provided with a plurality of first water distribution ports 30 a;
the second water distribution pipe 50 is arranged in the water storage space 11 and is positioned at the lower end of the shell 10, one end of the second water distribution pipe 50 is communicated with the second water inlet 10b, and the second water distribution pipe 50 is provided with a plurality of second water distribution ports 50 a; and
a plurality of water distribution caps 70, one of the first water distribution ports is provided with one of the water distribution caps 70, one of the second water distribution ports is provided with one of the water distribution caps 70, the water distribution cap 70 is provided with a guide structure, and water in the water storage space 11 flows along the guide structure.
Specifically, the water heat storage is to store heat by using sensible heat of water. Therefore, a reasonably designed cold and hot water based natural stratified charge cycle thermal storage apparatus 100 should achieve maximum thermal storage efficiency by maintaining as large a temperature difference of stored water as possible and preventing mixing of cold and hot water. In the water heat storage technology, the key problem is that the structural form of the heat storage tank should be capable of preventing the stored water from being mixed with the return water. The first water distribution pipe 30 and the second water distribution pipe 50 are arranged in the water storage space 11, and the mode of supplying water and returning water in the same tank is adopted, so that the investment of a heat storage tank can be saved, and the occupied area of the tank body can be reduced. Wherein, the first water distribution pipe 30 and the second water distribution pipe 50 are immersed in water to perform heat storage circulation.
The cold and hot water natural layering-based heat storage device 100 adopts a natural layering principle and utilizes different densities of water at different temperatures to realize natural layering. During the heat storage cycle, hot water sent from the boiler enters the water storage space 11 from the first water distribution pipe 30 at the top, warm water is discharged from the bottom, the water volume in the tank remains unchanged, referring to fig. 1, at this time, the second water distribution pipe 50 is a water outlet pipe, water enters the boiler plate heat exchanger after coming out from the second water distribution pipe 50, is changed into high-temperature water after being subjected to heat exchange by the plate heat exchanger, enters the upper part of the water storage space 11 through the first water distribution pipe 30, according to the different temperature and density principles of water, the hot water is stored in the upper part of the water storage space 11 to form a warm water layer 111, the bottom of the water storage space 11 is a cold water layer 115, the inclined temperature layer 113 is a cold and hot water junction, the inclined temperature layer 113 is thinner, and the higher heat storage efficiency of the heat. In the heat release circulation, the water flow direction is opposite, that is, the first water distribution pipe 30 is a water outlet pipe, because the high-temperature water density is low, warm water is stored at the upper part of the water storage space 11, and after coming out from the first water distribution pipe 30, the warm water is subjected to heat exchange with the plate heat exchangers of the heat exchange stations through the municipal pipe network, so that the circulating water at the tail end of a user is heated, changed into warm water after heat exchange, and returned to the bottom of the water storage space 11 through the second.
The thermocline 113 is a transition layer of hot water, and the thinner the thermocline 113 is, the less the hot water is mixed, and the higher the heat storage efficiency of the heat storage device 100 is due to the natural hot and cold water stratification. The thickness of thermocline layer 113 depends on the following factors: (1) density difference of hot water. (2) The longer the flow dispersion length of the water distribution pipe is, the smaller the flow per unit length is, and the smaller the turbulent flow is. (3) The installation height of the water distribution pipe is reasonable, and the thickness of the thermocline 113 can be reduced. The water distribution cap 70 is provided with the guide structure, the flow length can be increased through the guide structure, the water outlet flow speed is reduced, the disturbance is reduced, the thickness of the thermocline 113 can be effectively reduced, and therefore the heat storage efficiency of the cold and hot water natural layering circulation heat storage device 100 is higher.
In one embodiment, the guiding structure is an arc-shaped surface or an inclined surface. By such design, the diffusion length of the first diffusion port 30a and the second diffusion port 50a can be changed from the original hole diameter to the whole length of the guiding structure, for example, when the arc surface (which can be a part of a circle) is formed, the hole diameter is changed to the perimeter of the arc surface, or when the hole diameter is inclined, the hole diameter is changed to the length of the inclined surface, so that the diffusion length is increased, the water outlet flow rate can be reduced, the disturbance is reduced, the thickness of the inclined temperature layer 113 can be effectively reduced, and the heat storage efficiency of the heat storage device 100 based on the cold and hot water natural layering circulation is higher.
At this time, a coanda effect is generated between the water distribution cap 70 and the fluid, and the fluid (water flow or air flow) deviates from the original flow direction and tends to flow along the surface of the protruding object. When there is surface friction (also called fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid will follow the surface of the object as long as the curvature is not large. According to Newton's third law, the body exerts a deflecting force on the fluid, and the fluid must also exert a counter-deflecting force on the body, which in turn reduces the flow rate of the fluid.

Referring to fig. 4 to 6, in an embodiment, the water distribution cap 70 includes:
a first connecting piece 71, wherein the first connecting piece 71 is provided with the guide structure; and
the second connecting piece 73 is sleeved outside the first connecting piece 71, a gap is formed between the first connecting piece 71 and the second connecting piece 73, the first connecting piece 71 is limited on the second connecting piece 73, the second connecting piece 73 is provided with a through hole 73a, the through hole 73a is communicated with the first water distribution port 30a, and the second connecting piece 73 is connected with the first water distribution pipe 30;
and/or, the through hole 73a is communicated with the second water distributing port 50a, and the second connecting piece 73 is connected with the second water distributing pipe 50.
It is understood that the first connecting member 71 has a hemispherical shape, the second connecting member 73 also has a hemispherical shape, the diameter of the hemispherical shape of the second connecting member 73 is larger than that of the hemispherical shape of the first connecting member 71, and the first connecting member 71 and the second connecting member 73 may be integrally formed or separately formed. In order to facilitate the demolding, the first connecting piece 71 and the second connecting piece 73 are separated, the first connecting piece 71 is limited on the second connecting piece 73, and the limiting manner is various, such as screw connection or welding connection, and the like, and is within the protection scope of the patent.

Similarly, the second connecting member 73 is connected to the second water distribution pipe 50, the connecting manner may be a thermal melting or filament connection manner, the through hole 73a is communicated with and connected to the second water distribution port 50a, and the second connecting member 73 blocks the second water distribution port 50a, so that the water in the second water distribution pipe 50 flows out from the gap between the first connecting member 71 and the second connecting member 73. It should be noted that the water distribution caps 70 are the same in type, so as to ensure that the flow rates of the water flowing out from the first dispersion openings 30a or the second dispersion openings 50a are the same, so as to reduce the flow rate and the disturbance.
In an embodiment, referring to fig. 6, a plurality of limiting protrusions 75 are disposed at intervals on the inner side of the second connecting member 73, and the first connecting member 71 is limited on the plurality of limiting protrusions 75. The limiting protrusions 75 are arranged in a plurality, the limiting protrusions 75 are evenly arranged on the inner surface of the second connecting piece 73 at intervals, and the surface, close to the first connecting piece 71, of the limiting protrusions 75 is abutted to the first connecting piece 71 to limit.
Furthermore, a plurality of reinforcing ribs 77 are arranged on the surface of the first connecting piece 71 away from the second connecting piece 73, and one of the reinforcing ribs 77 is arranged corresponding to one of the limiting protrusions 75. Since the first connecting member 71 is impacted by water flow for a long time, in order to secure its service life, the overall structural strength of the first connecting member 71 is reinforced by providing the reinforcing ribs 77.

Furthermore, the value range of H1 is 300-500 mm, and the value range of H2 is 300-500 mm.
